IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 183,704, dated October24, 1876 application filed August 15, 1876.

To all whom it may concern:

Be it known that I, LAFAYETTE D. RAILS- BAGK, of Indianapolis, county ofMarion, State of Indiana, have invented a new and useful Improvement inPumps, of which the following is a description, reference being had tothe accompanying drawings.

Previous to my invention the use of stone or baked-clay cylinders hasbeen frequently employed by manufacturers of wooden pumps. and to suchclass of pumps their inventions have been especially adapted, and tosuch I make no claim.

My invention consists of a stone or bakedclay cylinder, which isprovided with iron flanges at the top and bottom, which are unitedtogether by means of bolts or boltrods. The flanges at the top andbottom are provided with screw-threads, to which are attached ironpipes, such as are used in driven wells; and the object of my inventionis to prevent or obviate the taste of iron in the water, which is commonwhen iron cylinders are used with iron pipes.

In the drawings I have represented my improved cylinder and itsconnections with iron pipes above and below, and for convenience ofillustration have represented the cylinder in section.

A represents the stone or baked-clay cylinder, in which operates thepiston-valve B by means of the rod J. At the top and bottom of thecylinder A are iron flanges D and E, which are secured together, withleather packing-rings K L between them and the stone cylinder, by meansof the bolts F F, which pass through ears formed on the flanges D E, inthe manner shown. Each flange D and E is provided with sockets O, whichare formed to receive the iron pipes H and G, in the manner shown.

By this method of uniting the stone or baked-clay cylinder to iron pipesI am enabled to remove the obnoxious taste of the water that passesthrough the cylinder, for this simple reason: the piston or suckerworking in a cast-iron cylinder, when at rest, allows a certain amountof oxidation to take place in the cylinder, and when the sucker orpiston valve is worked the friction removes this oxide, and allows it toimpregnate the water, while in the stone cylinder no such impurities canbe formed to impregnate the Water.

I am aware that stone cylinders or cylinders formed of baked clay areold, and that there are some four different patents on them and theirconnections with wooden pumps, which were granted to A. N. Barkhurst,and such inventions I do not claim.

What I claim as new, and wish to secure by Letters Patent, is

The combination, in a pump having a stone, baked-clay, or glasscylinder, A, in which operate suitable valves B O, as shown,of the ironpipes H G, secured to said cylinder by means of iron flanges D E, saidflanges being provided with screw-threads to receive the pipes, andunited together by bolts F F, all arranged in the manner and for thepurposes set forth and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
